The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern I the art to practice it.

This invention relates particularly to an improvement in that class of seed sowing machines in which the seed fed from a hopper into a delivery-spout or discharger is thrown or broadcast from the machine by rotation. of the said discharger, effected-by the movement of the carriage upon which the seeding mechanism is mounted, or of which such mechanism forms a part, the movement of the discharger being directly effected by the movement of the carriage, the discharger being directly or indirectly connected to one of the carriage-wheels by a geared or bolted connection, such a machine being shown, for instance, in O. W. Cahoons patent of September 1, 1857, reissued may 11, 1858. w l

. In all Gahoon sced-sowers, and others similar in organization or general method of operation, there is a positive connectionbetween the discharger and the driving carriage-wheel, so that the'discharger is driven V ineither direction of movement of the carriage, and cannot be stopped except by throwing err the belt, this, or shutting 0d the passage of the seed from the hopper, being the only method of preventing the sowing of the seed when the carriage is in motion.

The object of my invention is to so organize the mechanism that, when the carriage backs, the sewer" This hopper is stationary relatively toth'e frame 1-,

and opens at bottom-into the dischargere.

The mouth of the discharger is fixed on the end of a rotary hon'zontal shaft, f, its tear or delivery mouth being in a vertical plane.

The shaft rotates in suitable hearings on the framework, and has .at its front end a pinion, g, meshing ,into and driven by a gear-wheel, h, on the inner end" of a cross-shaft, 'i, at whose outer end is a clutch, k, that engages with a sliding sprocket-pulley, l, sliding over the shaft, and rotating loosely on the shaft when not in engagement with the clutch k,'and rotating with said shaft when in engagement with the clutch.

This sprocket-pulley is"connec ted by a spocketchain or belt, in, with a sprocket-wheel, a, on one side of one of the wheels 0, as seen in the drawing, so that rotation of the driving-wheel c, or movement of the carriage, always effects rotation of the sprocketpulley l.

The clutch-teeth are so formed that they unclntch when the pulley l is turned by the rear movement of the carriage, so that no movement is then imparted to the rotary secd-discharger, while, if the pulley lhe pressed against the clutch It, when the carriage is drawn forward the pulley will rotate the clutch and the disch'arger geared to the clutch-shaft.

A fork, 1), at the end of a hand clutch-lever, enters a groove, 0', around the pulley s, the lever being fulcrnmed at t, and its handle being located in convenient position to be grasped by the rider.

Itwill thus be seen that, without throwing off any belt or leaving the carriage, the driver or operator can instantly throwthe discharger into or out of rotative operation, as circumstances may require, as'in turning, going to and from the grounds to be sowed,

and when passing over grounds or pieces of ground not to be sowed.

I- claim, in combination with the seed-discharger e, or its equivalent, and its driving mechanism, operated by the movement ofthe carriage, the intermediate clutch" and clutch-pulley operating to automatically throw the discharger outof action when the carriage backs, substantially as described.
